I manually click Sleep but the iMac immediately reboots instead of going to sleep I'm having two related issues, as follow. I am religious about Time Machine backups and use iCloud Drive for desktop and document sync. EtreCheckPro is the only utility that reports any problems. I have run Apple's Online Hardware Test, and it reports everything OK. (That's why you'll see numerous application installs over the last few days.everything had to be re-installed.) After that, the old delay and beach-balling problems started to recur. From there, Disk First Aid said the drive was good, so I re-installed the OS (Monterey) and proceeded to rebuild everything from the Time Machine backup. Finally, I have no idea what my options are for replacement.Ībout ten days ago the iMac failed to wake from sleep and the only option available was to boot into Internet Recovery mode. Also, I don't know how to tell which component of the Fusion Drive, the ssd or the spinning hard drive (or both), is failing. I suspect that's what's causing the problems, but I'm not sure. EtreCheckPro reports as a "major" problem that the hard drive is slow. I have the iMac with the 1TB Fusion Drive. IMac (Retina 4K, 21.5-inch, 2019) running slow with beach-balling while opening apps and documents. *that is what seems to have been going on, anyway, last night and this morning That is a contradiction of goals.Ĭan anyone clarify what if anything I am doing wrong with Ventura? Maybe it’s just my expectations. Somehow, my external SSD trying to connect over and over* does not seem like a good thing - so I assume it’s because I set that “Prevent automatic sleeping when the display is off” switch to “false.” But if I set it back to “true,”I assume my Mac is NOT sleeping. I assume.Īfter logging in, backups resumed once the connection was restored to the TM SSD. Clearly nothing is (supposed to be) happening at night so there would be no physical backups but TM should acknowledge the attempts as scheduled. And both days, the last backup was the night before, not what I expected to see. I had never noticed that message with Monterey. When I logged in, I saw that my Mac was trying to connect to the external drive. These attempts occurred within a couple of minutes of each other, not at all like a TM update. I heard it last night apparently coming on (well, the internal fan) several times, and again this morning. BUT there is some odd behavior with the external SSD I am using with TM. I turned that switch to “false” two days ago, and now it seems to be sleeping. The option to leave the disks running while the display is off (“Prevent automatic sleeping when the display is off”) is now defaulted to “true.” As a result, when logging on in the morning, the password dialog box came up “instantly”, indicating it had not been sleeping. I recently upgraded to Ventura (13.0.1), and now I have a lot of concerns. I was not sure quite what TM was doing but did not notice problems. It seemed that my iMac was indeed sleeping. I also started using Time Machine during Monterey - previously, I did my backups manually.Īll well and good with Monterey. So I convinced myself to try it during Monterey. But I have read many times over the years that Apple prefers the devices left on, presumably because boot-up performance is so bad (yes, updates too). I am a long-time Mac user but I never started the habit of leaving my machine on overnight - it has to do with paranoia from a hacking story a very long time ago. It seems that I can either have the Mac sleep overnight OR have TM operate properly overnight, but not both. I am not really sure my Mac is sleeping and am concerned about missing settings with Ventura (that were not needed with Monterey) to assure proper TM operation overnight. Tl dr - When I leave my 2018 iMac on overnight with Ventura and Time Machine, I am seeing what I believe to be unusual, disconcerting behavior.
